Font Info > Features > Can't undo some actions

I can undo deleting a class/feature, but can’t undo creating or renaming.

Try this

Create a class (and name it for good measure) > delete it > create another new one > command+Z

(it will undo the second step, not the 3rd)

and try this.

Click into edit field > type something > click into class name > click again to edit > type something > command+z

(it will undo the second step, not the 4th)

In the second case I actually end up with 2 flashing cursors at the same time (one in each field) which is something I’ve never seen before.
